Versuchsvorschrift

The product of Example 21, Step 2 (50 mg, 0.158 mmol, 1.00 equiv), 5-amino-3-ethylindazole (25 mg, 0.158 mmol, 1.0 equiv), and EDC (36 mg, 0.189 mmol, 1.20 equiv) were suspended in 0.5 mL DMF. Et3N (0.026 mL, 0.189 mmol, 1.2 equiv) was added and the solution was stirred at room temperature for 18 hrs. The reaction mixture was diluted with EtOAc and 1N HCl. The phases were separated, and the organic phase was washed twice with 1N HCl, once with satd. NaHCO3, and once with satd. NaCl. The organic phase was dried over Na2SO4, filtered, and concentrated en vacuo. The residue was purified by flash chromatography (20-100% EtOAc in Hexanes) to provide 25 mg (34%) of the title compound as an off white solid. MS (ES+) m/e 461 [M+H]+
